UNIT_TYPE_STUNNED not working??

I tried detecting if my unit is stunned with IsUnitType(myUnit, UNIT_TYPE_STUNNED) but it turns out that it doesn't show true if it is stunned. I tried using 'ANbh' (neutral hostile bash) as the stunning ability. So is this function bugged or I'm using it wrong?

Detect the buff with GetUnitAbilityLevel(), God only knows what Blizz was thinking with UNIT_TYPE_STUNNED.

So that means I need to detect the buff for each stunning ability? Aww man... its kinda weird since UNIT_TYPE_SNARED actually works fine though. Thanks for the answer anyway :)

Nope, you need to check for buffs.

And if you use a single, general stun buff for your stun spells, this shouldn't be too big of a problem.

Hmm.. I see. But what I'm not sure is the stun buffs for impale, volcano and Cluster rockets. Are they supposed to have their own stun buffs or I can actually use the general stun buff?

EDIT: oh and just to share what I have found, the UNIT_TYPE_SNARED and UNIT_TYPE_SLEEPING actually works as how they should be. And "SNARED" includes entangling roots, ensnare and web spells.

I think 99% of the stuns are "BSTN". the rest are "BPSE". Check both.

Or just have all stuns in your map use the same buff like most sane mapmakers.
